Query about Enhanced Out-Of-Memory handling

[bill4carson]

Hi, all

Since there is a practical needs for user application with the ability 
to sense kernel memory use pressure,
http://elinux.org/Memory_Management  gives some approach on this as below:

OOM notification in cgroups
mem_notify patches
Google cgroup OOM handler
Nokia OOM enhancements

AFAIK, it seems none of these have been merged into mainline or updated 
continuously,
I'm not so familiar with mm system, so may I ask which known approach is 
best to work with mainline kernel now?
